This was quite possibly the worst idea for title naming that I could have thought of. Anyway, I played around a bit more tonight, and I thought that I would give an update to the three people that are waiting with bated breath.

Anywho, I decided to continue trying to map the data from the netcdf file onto a projection, and here’s what I ran into.

It looks like the basemap module is installed (as basemap) but that it depends on matplotlib > 0.98 and 0.91 is installed. I tried to be tricky and move my locally installed matplotlib over to the sage/local/lib/python2.5/site-packages directory but then that version of matplotlib needed a newer version of numpy than what was installed. At this point I tried

hostname $> sage -upgrade

to see if updated packages/modules were available. This started a huge chain reaction of downloads and source compiling to get to the latest, greatest versions. This process took exactly 59m10.482s to complete (I know because it told me!).

But once again, I get this error:

sage: from basemap import basemap

ImportError: your matplotlib is too old – basemap requires version 0.98 or higher, you have version 0.91.1

At this point though, it’s not working on either the linux or OSX platforms due to outdated dependencies, so either I need to find another way to plot mapped projections or use something else.

Again, this isn’t a knock against Sage, because I really don’t think that is an ideal test for this software. But honestly, a lot of why I went for this approach was to avoid having to use separate approaches for data manipulation and visualization, and this would be a common task. Matlab’s mapping toolbox is useless to me for plotting, so I end up using m_map, which is still not as good as GMT, but it gets the job done in house.

My main thoughts at this point are that it seems easy to get into dependency hell here, as one module upgrade can force another, and so on. At this point it’s another block of time spent on setup, and no result. Time to stop for the time being.
